Luckily, when one door is closed, another often opens—and this new door comes in the form of a new S-off method for devices running software version 3. XDA Recognized Developer beaups managed to bring his Rumrunner S-off method to the device. As described by the developer:

software version 1.xx – use facepalm
software version 2.xx – use moonshine (2.06 version of moonshine DOES work with 2.07 devices)
software version 3.xx – use rumrunner

If you have a recently updated device and you want to get the S-off goods, make your way over to the original thread to get started.
